Brief summary
This study seeks to evaluate and compare the pharmacokinetics of a novel micellar silymarin formulation with that of a standard silymarin formulation.
Interventions

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| AUC: the area under the concentration-time curve | 0 (baseline; pre-dose), 0.5, 1, 1.5, 2, 2.5, 3, 4, 5, 6, 12, 24 hours (post-dose) | To determine the gastrointestinal absorption of orally ingested silymarin in healthy adult volunteers and compare the Area under the plasma concentration versus time curve (AUC) with that of other capsules containing silymarin. |
| Cmax: maximum plasma concentration | 0 (baseline; pre-dose), 0.5, 1, 1.5, 2, 2.5, 3, 4, 5, 6, 12, 24 hours (post-dose) | To determine the gastrointestinal absorption of orally ingested silymarin in healthy adult volunteers and compare the peak plasma concentration (Cmax) with that of other capsules containing silymarin. |
| Tmax: the time point of maximum plasma concentration | 0 (baseline; pre-dose), 0.5, 1, 1.5, 2, 2.5, 3, 4, 5, 6, 12, 24 hours (post-dose) | To determine the gastrointestinal absorption of orally ingested silymarin in healthy adult volunteers and compare the time point of maximum plasma concentration (Tmax) with that of other capsules containing silymarin. |
| MRT: Mean residence time | 0 (baseline; pre-dose), 0.5, 1, 1.5, 2, 2.5, 3, 4, 5, 6, 12, 24 hours (post-dose) | To determine the gastrointestinal absorption of orally ingested silymarin in healthy adult volunteers and compare the mean residence time (MRT) with that of other capsules containing silymarin. |
| T1/2: elimination half-life | 0 (baseline; pre-dose), 0.5, 1, 1.5, 2, 2.5, 3, 4, 5, 6, 12, 24 hours (post-dose) | To determine the gastrointestinal absorption of orally ingested silymarin in healthy adult volunteers and compare the elimination half-life (T1/2) with that of other capsules containing silymarin. |
